Abstract

Indonesia has the greatest potential for geothermal energy in the world. Geothermal has an important role as an alternative fuel because it is a renewable energy source, but its use has not been maximized. One of the areas that have the greatest potential for geothermal energy in South Solok, West Sumatra. Therefore, this study was conducted to determine the geothermal system in the South Solok area, West Sumatra by using the gravity method. The gravity data processing stage requires some software to get the CBA value(Complete Bouguer Anomaly), map contours of the CBA. Anomaly separation with the butterworth filter method, determination of residual anomaly slice points, and 2D modeling of geothermal systems. Based on modeling, the qualitative interpretation interprets the Complete Bouguer Anomaly map which is suspected as a geothermal prospect area is a low anomaly ranging from 7.9 mgal - 9.4 mgal which is marked in dark blue. Meanwhile, quantitative interpretation produces modeling of the AB and CD slicing with a total of four layers. This layer consists of clay rock as a cap rock, sandstone as a reservoir, granite as a heated rock as a heat source, and the last layer in the form of magma as a heat source. The anomaly modeling of these two sections is dominated by granite rock with a density value of 2500 kg/m3 for the AB section and 2550 kg/m3 for the CD section.

Abstract

Telah dilakukan survei geolistrik resistivitas di lahan UIN Jakarta, yang berlokasi di Desa Cikuya, Solear, Tangerang. Tujuan survei untuk mengetahui kondisi bawah permukaan lahan UIN tersebut dan hasilnya dapat menjadi rekomendasi bagi UIN Jakarta dalam pengelolaan lahan lebih lanjut. Metode yang dipilih adalah metode geolistrik resistivitas sounding dan mapping, dengan konfigurasi elektroda Schlumberger dan Dipole-dipole. Alat yang digunakan Iris Syscal Junior dan pengolahan data menggunakan Software IP2Win untuk data sounding dan Software Res2dinv untuk data mapping. Hasil yang diperoleh dari aplikasi metode geolistrik resistivitas memberikan gambaran bawah kondisi permukaan lahan tersebut terdiri atas lapisan alluvium, lempung pasiran, dan batu pasir, dan batuan bedrock. Berdasarkan hasil interpretasi terebut maka lahan tersebut dapat dimanfaatkan di bidang pertanian dengan ditanami dengan tanaman palawija, dapat pula untuk pengembangan wisata dengan ditanami dengan tanaman bunga seperti bunga matahari. Apabila pada lahan tersebut akan didirikan bangunan maka bangunan yang direkomendasikan adalah bangunan maksimal 2-3 lantai. Apabila lahan digunakan untuk hunian maka kebutuhan air dapat dipenuhi dengan keberadaan akuifer atau lapisan pembawa air cukup baik yang ditunjukkan dengan lapisan batu pasir sebagai lapisan pembawa air, dan juga adanya lapisan lempung sebagai lapisan akuifer. Pengadaan air ini dapat dilakukan dengan pengeboran sumur air tanah yang dapat dilakukan pada kedalaman ±> 17meter. Sedangkan untuk keberadaan bahan tambang berupa gamping dan pasir perlu dilakukan kajian ekonomis apabila dieksplorasi lebih lanjut.

Abstract

To find out the potential of hematite in Pulau Beringin, the data analyzing must be done thoroughly towards the hematite on the surface of the soil by doing the Geolistric method. Geolistric method is a Geophysic’s method that learns about the characteristics of electricity inside the earth and detect them on the surface of earth. One of the methods in Geolistric is Induce Polarization (IP), which is the process of electric polarization that can be used to identify areas containing the hematite. The measurement result of 8 strips, anomaly IP can only be found in strip K. , that shown at point K.17 with chargeability value 60mdt, meanwhile the resistivity value at point K.17 is 30 Ωm, that contain shale and granite. Moreover, this result doesn’t identify the existence of hematite in the strip due to lack of chargeability and resistivity value in the other strips. Keywords: Geolistric method, Induced Polarization (IP).

Abstract

The Mount Hamiding area has one of the largest geothermal potentials in Indonesia to be exploited. Therefore, this research was conducted with the aim of knowing the subsurface structure in the area using the gravity method. To correlate gravity data in order to obtain parameters to measure the increase in surface temperature using supporting data is land surface temperature. Derivative analysis and 2D modeling carried out by forward modeling is one method that can strengthen the geothermal potential in the area. Based on the Land Surface Temperature map, the temperature around the geothermal prospect area is 22 – 25 0C. The results of the derivative analysis show that the geothermal prospect of Mount Hamiding is controlled by two different faults, a fault due to the depression of the old Hamiding caldera and a local fault under the surface of Mount Dukono, which is confirmed as a reverse fault. While the 2D modeling identified the geothermal reservoir layer, which is estimated to have a density of 1.59 gr/cc and consists of a mixture of tuff and minor lava, where the contents of this reservoir are water dominant due to the relatively low-density value with a depth of -411 – (-1280) m, above the reservoir layer it is suspected that the tuff and clay insert layer has a density of 2.56 gr/cc with a depth of 310 – (-1280) m, and the covering layer which is presumed to be a clay cap layer has a density of 1.39 gr/cc with a depth of 870 – (-620). ©2022 JNSMR UIN Walisongo.

Abstract

Physical education aims to promote physical, mental, and emotional health. Facilities and infrastructure are needed to achieve the learning objectives of PJOK. That way the facilities and infrastructure can meet satisfaction with PJOK learning. There have been many studies conducted before regarding surveys of sports and health physical education learning facilities and infrastructure, but researchers want to examine the level of student satisfaction with sports and health physical education learning facilities and infrastructure that have not been researched much before. The purpose of this study was to see the level of student satisfaction with PJOK learning facilities and infrastructure at SMP Muhammadiyah 3 Ampel. Quantitative descriptive research method involving 60 students from all students at SMP Muhammadiyah 3 Ampel.  Data collection techniques use questionnaires, observations, and documentation. Analyze the data using the help of Microsoft Excel. The results of the study obtained, that the level of student satisfaction with the PJOK learning facilities and infrastructure at SMP Muhammadiyah 3 Ampel was included in the category of "Quite Satisfied", with some of the facilities and infrastructure owned by SMP Muhammadiyah 3 Ampel that were not adequate and the number of facilities that were still lacking. From the results of the research that has been carried out, it is hoped that it can provide benefits for the management of school facilities and infrastructure to increase student satisfaction with the facilities and infrastructure owned.

Abstract

Abstract. The existence of Indonesian geothermal is estimated to be spread in 331 locations, one of which is Sembalun, East Lombok Regency. Therefore, this study was conducted to analyze the subsurface structure of geothermal prospect areas in the area using gravity methods. Gravity data used is satellite data as much as 4275 measurement points that have been corrected free air (FAA). The data processing stage resulted in a Complete Bouguer Anomaly (CBA) map with low anomaly values to be the target of research ranging from 58.9 – 115.7 mGal located in the east (Sembalun-Bumbung) and northeast (Sembalun-Lawang). The prospect of geothermal is controlled by the Talaga fault and Pusuk fault on the caldera floor (Sembalun-Lawang). In addition, the Tanakiabang fault and the Orok fault are near the manifestation of Sebau Hot Springs and on the Caldera floor (Sembalun-Bumbung). The results of 2D modeling correlated with 3D modeling conducted inversions showed geothermal sources are estimated to have a density of 2.68 gr/cc – 3 gr/cc consisting of hornblende andesite lava rocks with a depth of >2500, reservoir layer in the form of sand that has a density of 1.4 gr/cc - 1.72 gr/cc with a depth of 700 - 1200 m and a layer of a hood in the form of alluvium rocks that have a density of 1.8 gr/cc - 2.2 gr/cc with a depth of 0 - 500 m.
